Every photo of the car resembles a moment in time.
When these photos are taken every second, the distance in between these photos will tell you something about the speed in that timeframe.

Do you remember?
You can't see the force itself, but you can recognize that a force is at work
when you see the result of an objects interaction with that force:
a change in speed
a change in direction
a change in shape (plastic or elastic)

Force and motion
With a constant speed,
the resultant force is zero.
But if there is a resultant force, the direction of this force in relation to your motion will decide if you will start
to accelerate or decelerate
Slide 13 - Diapositive
G-forces
G forces is about the weight you feel. It is the force an object exerts on its support area. 2 G means that you feel as if your weight has increased 2 times.
This feeling is caused by a combination of the gravitational force on your body and the force you feel as the result of an acceleration or deceleration

Scalars & vectors
Scalars are quantities which are described by magnitude only.
Vectors are quantitues which are described by both a magnitude and a direction
